18 mg of methyl 6-aminohexanoate hydrochloride (0.1 mmol, 1.0 equivalent) were initially charged, and 29 mg of 8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid Example 6A (0.1 mmol, 1 equivalent) in 0.3 ml of DMSO, 41.7 mg of (benzotriazol-1-yloxy)bisdimethylaminomethyliumfluoroborate (TBTU, 0.13 mmol, 1.3 equivalents) in 0.3 ml of DMSO and 26 mg of N,N-diisopropylethylamine (0.2 mmol, 2 equivalents) were added in succession. The mixture was shaken at RT overnight, 0.4 ml of 2 N sodium hydroxide solution was added and the mixture was once more shaken at RT overnight. The solvent was then evaporated and the mixture was purified by preparative HPLC (Method 10). This gave 11 mg (26% of theory; purity: 100%) of the title compound.
